Which we both agree we dont want, right?

Maybe we are using different terms and not 
understanding each other.  But if what you 
mean by "N=2" you are meaning TRAP all
values of N=2, then that wont work for
two reasons.

1) It wont let the home stations use WIDE3-3
2) It wont even let anyone use WIDE2-2, because
it will trap them.  That means it will digipeat WIDE2-2
only once and callsign-substitute and the packet
will go no farther.  So  you are forcing everyone
to one hop actually...

Sorry, If I am not understanding your point, but
in a 3 hop area (meaning everyone agrees thta
3 hops is OK in an area, then that means fixed
stations are recommended to use WIDE3-3 or
less and mobiles are recoemended to use 
WIDE1-1,WIDE2-2.  And there are no settings
you can place at the digi that will prevent a mobile
from using WIDE1-1,WIDE3-3.  We have to use
user education to prevent that.

Does that help?
